    Failure causes of lithium battery- Failure during shelving

    Oct , 08 2022
    In the service life of the power battery, most of the time is in a state of shelving. Generally, after a long period of shelving, the performance of the battery will decline, generally showing an increase in internal resistance, a decrease in voltage, and a decrease in discharge capacity. There are many factors that cause the degradation of battery performance, among which temperature, state of ch...

  • Advantages and disadvantages of lithium iron phosphate battery and ternary lithium battery

    Advantages and disadvantages of lithium iron phosphate battery and ternary lithium battery

    Sep , 05 2022
    1. Energy density: The energy density of ternary lithium is about 1.7 times that of lithium iron phosphate, so the volume and weight of ternary lithium batteries will be smaller than those of lithium iron phosphate batteries, and the car load will be smaller. 2. Safety performance: lithium iron phosphate battery will perform better in acupuncture test, and in high temperature environment, the stab...

  • Overview of the lithium battery formation process

    Overview of the lithium battery formation process

    Sep , 05 2022
    Lithium- ion battery formation process includes constant current, constant voltage and intelligent charging. The polarization phenomenon of constant current charging is serious, and its initial current is low, the current at the end of charging is high, the charging time is long, the energy waste is serious, and the battery life will be reduced. During constant voltage charging, the current is rel...

  • Influence of SEI film on the performance of Li-ion battery

    Influence of SEI film on the performance of Li-ion battery

    Sep , 05 2022
    After extensive research, it has been found that the properties of SEI films greatly affect the performance of Li-ion batteries. During the formation process, the amount of the SEI film formed represents the amount of lithium in the consumed lithium-ion battery, which directly determines the capacity of the lithium- ion battery. Therefore, in the process of forming the SEI film, the less lithium i...

    Effect of electrolyte on SEI film

    Sep , 05 2022
    The electrolyte is the main source of the reduction reaction reactants for the formation of the SEI film , and both the electrolyte solvent and the lithium salt will affect the composition of the SEI film. When the main components of the electrolyte are basically fixed, the performance of the SEI membrane can only be improved by other means. The researchers found that the formation of the SEI film...

    SEI film formation mechanism

    Sep , 05 2022
    During the formation of the SEI film, various reduction reactions are carried out by the electrolyte solvent, lithium salt, additives, and trace air impurities. This series of reactions is not only affected by the inherent properties of substances such as reduction potential, reduction activation energy, and exchange current density, but also by other factors such as temperature, electrolyte salt ...

  • Solar battery life time

    Solar battery life time

    Aug , 08 2022
    There are two ways to answer this question and the first is to determine how long a solar battery can power your home. In many cases, a fully charged battery can run your home overnight when your solar panels are not producing energy. To make a more exact calculation, you’ll need to know a few variables, including how much energy your household consumes in a given day, what the capacity and power ...

  • Thermal Runaway of Lithium Battery

    Thermal Runaway of Lithium Battery

    Aug , 08 2022
    One of the main causes of danger for lithium-ion cells is related to the phenomenon of thermal runaway. This is a heating reaction of the battery in use, caused by the nature of the materials used in the chemistry of the battery. Thermal runaway is mainly caused by the solicitation of batteries under specific conditions, such as overload under adverse climatic conditions. The result of a thermal r...
